Abstract: To address the limitations in the existing anonymous handover authentication (AHA) protocols, we propose a novel certificateless-based public key cryptography (CL-PKC) AHA protocol using elliptic curve cryptography (ECC). The protocol can achieve all the security requirements of AHA protocol and provide countermeasure against privilege escalation. The beauty of our protocol is that it is autonomous, where nodes only need to contact the authentication server (AS) once for pseudonym set and thereafter they can renew their pseudonyms on their own. The formal protocol analysis shows that the protocol achieves mutual authentication and session key establishment. Moreover, we show that the protocol is secure in the random oracle model based on elliptic curve discrete logarithm assumption (DLA). The performance evaluation demonstrates that the proposed AHA protocol is very efficient in terms of computation cost and communication overhead than related protocols.
